Alt-text: Umwelt is the idea that because their senses pick up on different things, different animals in the same ecosystem actually live in very different worlds. Everything about you shapes the world you inhabit--from your ideology to your glasses prescription to your browser window size.

As an aside, there's some wacky hijinks going on, presumably April Fool's related. The source acts as if it's still 1036, and the picture only loads in Chrome for me.

It goes further... in Safari the picture wont load and the alt text reads "... prescription to your web browser" not "... web browser size" but in Fire Fox it ha no problems. Also, you see a different comic the wider your browser window is. Well played

JimsMaher: I can't see your image within the forum thread (though I can if I right-click). I don't think the forum software is playing nicely with your image host. Or possibly there's another explanation. Probably the image host is changing the URL...

I have chrome and windows 7, and it's showing the Northern Lights in Canada versionI used IE7 and it showed me the "too too quiet" raptor comic.I also saw the snake version originally, but now I can't get it back.

I'm on OS X 10.6.8 Using Chrome I get the same as Jim. Using Firefox I get the snake one (which goes through a portal if the picture is big enough). In Safari and Opera no image displays.Does anybody know enough to look through the page source and see what's happening?

From what I've been able to figure out, the comic displayed depends on the browser user agent (user agent switcher addon), and location.

I've been changing my user agent and get a new comic every time.

Also, a more brute force method is to get the comic URL and simply change that and search for others. I used grease monkey to grab source and get an image URL.

So my first comic was this: http://imgs.xkcd.com/a1panels/a1_13p1s1_0.png

My understanding so far is that:"a1_XX" chooses a specific comic (a1_13 for me)"pX" grabs a panel from that comic (p1)"sX" seems to move that panels location among the comic (s1)"_X" is an alternative panel that seems to change based on location (_0)

So change the value where the X's are and you should be able to see every possible comic/alternative by loading all the URLs.

ex:http://imgs.xkcd.com/a1panels/a1_1p1s1_0.pnghttp://imgs.xkcd.com/a1panels/a1_1p1s1_1.png (Same panel, slightly different content)http://imgs.xkcd.com/a1panels/a1_1p1s2_0.png (Slightly different scene, maybe shifted in order when normally displayed?)http://imgs.xkcd.com/a1panels/a1_1p2s1_0.png (Next panel in comic)

when i ran it on Win 7 and chrome, i got this one: http://imgur.com/VlhUJ

when i ran firefox i got the too quiet one. I tested it out on a linux vm and it still showed the same ones. on IE i got nothing as well. could it be location based? I live in MI, so the comic for chrome seemed tailored for me, but that could just be chance.

This is akin to the source. It will allow us, I presume to post to our individual onesI used chrome, went to inspect element and got the image from ghenkEggov8.See what you guys can do?

How did you use the URL? That's only one panel of the comic.

EDIT: Nevermind, I looked at your post's source

It seems to me that the http://umwelt.xkcd.com/story/ghenkEggov8 link runs a PHP script that uses client data to generate a set of panels to display, which waldo.js arranges properly. That being said, I'm tired and by no means versed in Javascript or PHP.
